new firmware now wont boot! help pls

last night i installed the latest firmware update for my crucial m4 128 gb ssd and today my computer wont boot past the bios. "reboot and select proper boot device or insert moot media in slected oot device and press a key." is my ssd toast from the firmware? asuming its not, is formating my only solution? in my bios ahci is enabled and it is still set to boot from the m4
